Question

A muscle cell breaks down glucose using the Krebs cycle.

Which best explains this cycle?



A.
The electron transport system breaks down glucose to create most of the ATP needed by the cell. The Krebs cycle uses NADH and FADH2 to create the ADP necessary for the generation of ATP. The Krebs cycle is important for the role it plays in glycolysis after ATP is created in the electron transport system.

B.
Once pyruvic acid is extracted from the ADP found in glucose, it enters the Krebs cycle, where most of the ATP required by the cell is produced. NADH and FADH2 then make a smal

Answer 1

l amount of ATP when they enter the electron transport system. The Krebs cycle is important for the role it plays in extracting ADP from the glucose molecule in order to produce pyruvic acid.

C.
During glycolosis, glucose is broken down, then the products of glycolysis enter the Krebs cycle. While some ATP is produced through the Krebs cycle, most ATP is formed when the products from the Krebs cycle enter the electron transport system. The transfer of energy from glucose to ATP occurs during the Krebs cycle.

D.
Glucose is broken down into pyruvic acid through the Krebs cycle. As glucose enters the Krebs cycle, it is transformed into NAD+ , FAD, and ADP. The Krebs cycle is important in the creation of these materials for the production of ATP in the electron transport system.

Answer 2

Please help. I think it's either A or B.

Answer 3

Will medal ^_^

Answer 4

I think it is C, how did you get A or B?

Answer 5

it doesnt exactly sound like C

Answer 6

because of this sentence - " The transfer of energy from glucose to ATP occurs during the Krebs cycle. " no it doesnt.

Answer 7

@Somy I only say C since that last sentence can be referred to as ATP-equivalent for high school.

Now looking back at it, I might lean towards B a bit more.

B or C, its honestly just worded horribly.

Answer 8

Glucose is broken down into pyruvic acid through the Krebs cycle. As glucose enters the Krebs cycle, it is transformed into NAD+ , FAD, and ADP. The Krebs cycle is important in the creation of these materials for the production of ATP in the electron transport system.

Answer 9

Glucose is broken down into pyruvic acid through the Krebs cycle. = no
As glucose enters the Krebs cycle, it is transformed into NAD+ , FAD, and ADP. = part of glucose no
The Krebs cycle is important in the creation of these materials for the production of ATP in the electron transport system. = yes

so D is pretty much wrong

Answer 10

A and B dont sound good either
wording is indeed horrible and now that i read it, you initial option of C is better than the rest @alphadxg

Answer 11

your*

Answer 12

Yes, Indeed. I still think B or C, I'm very familiar with this subject and I would still go with my initial C answer.

Hopefully the user has figured the answer out by now.

Answer 13

well you can take down B Once pyruvic acid is extracted from the ADP = NO
found in glucose, it enters the Krebs cycle, where most of the ATP required by the cell is produced.= NO
NADH and FADH2 then make a small amount of ATP when they enter the electron transport system. =NO
The Krebs cycle is important for the role it plays in extracting ADP from the glucose molecule in order to produce pyruvic acid. =NO
B is fully wrong.
